Embodiment 2
[0052] In the second embodiment, two rows are selected sequentially, and the polarity of travel is selected by row inversion. The execution process is convenient, and the inversion process saves power, time and efficiency.
[0053] The third embodiment of the present invention is given below. In the third embodiment, the method of point inversion and row selection according to the algorithm is adopted. see Figure 11 The flowchart of the shown embodiment three includes the following steps:
[0054] S31: The control chip outputs a timing control signal according to the pulse timing.
[0055] The control chip sends a timing control signal through the pin TP1, that is, rises from low level to high level.
[0056] S32: The control chip randomly selects two rows of liquid crystal molecules, and transmits the data to be displayed to the display chip.
[0057] In this embodiment, the control chip transmits the data to be displayed to the display chip. First, the control chip needs...

The invention aims at providing a method for controlling liquid crystal molecular polarity inversion, a device and an LCD device thereof. The method comprises the steps of: within a control time sequence, setting and selecting more than two liquid crystal molecular rows according to the preset selection; and reversing the polarity of liquid crystal molecules in the liquid crystal molecular rows. The device comprises a selecting module and a polarity control module, wherein the selecting module is used for setting and selecting more than two liquid crystal molecular rows within a control time sequence according to the preset selection; and the polarity control module is used for reversing the polarity of liquid crystal molecules in the liquid crystal molecular rows. The LCD device adopts a control chip and can be an LCD TV or display. Compared with the scheme of controlling the polarity inversion of one liquid crystal molecular row within a control time sequence, the scheme of the invention can control the polarity inversion of a plurality of liquid crystal molecular rows within a control time sequence, thus saving the control time sequence, reducing the system power consumption and improving the liquid crystal molecular inversion efficiency.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method, a device and a liquid crystal display device for controlling polarity reversal of liquid crystal molecules. Background technique [0002] In the manufacturing process of LCD TVs, it is necessary to realize the control of the liquid crystals in the LCD TVs, so that during the use of the LCD TVs, the LCD TVs will be reversed from time to time as the image is displayed, so as to prevent the liquid crystal molecules from remaining the same for a long time. polarity can cause damage. [0003] In the manufacturing process of current LCD TVs, in order to pursue better display effects, line inversion or dot inversion is often used to control liquid crystal molecules. Using this control method can improve the display effect of liquid crystal molecules. In practice In the process of use, the reversal of the liquid crystal molecules is controlled by timing, so that...
